摘要:
A reflective image display comprising of a reflection enhancing layer comprising of a plurality of approximately spherical indentations is placed adjacent a sheet comprising of a plurality of hemispherical protrusions. The radii of curvature of the spherical indentations substantially coincides with the center of curvature of the adjacently located hemispheres to enhance the white paper-like appearance of the display while efficiently enabling optional color filters to yield saturated color.
摘要:
Die Erfindung betrifft einen Reflexstreifen (10) zum Anbringen an einem Grundmaterial, insbesondere an einer Schutzbekleidung für Einsatzkräfte, wobei der Reflexstreifen (10) einen Grundstreifen (1) aus einem schwer entflammbaren, fluoreszierendem Gewebe mit hoher Atmungsaktivität aufweist, und in dem Grundstreifen (1) zumindest in einem Teilbereich der Fläche zumindest ein Bereich, insbesondere ein Streifen (2) aus retroreflektierendem Material eingearbeitet ist.
摘要:
An identification device (10) comprises a retroreflector (12) for receiving an incident beam of radiation (14) from a detection unit (15) remote from the device and selectively retroreflecting the incident beam back to the detection unit. The retroflector (12) comprises a substantially spherical graded refractive index lens (16) and a reflective part (18) for reflecting the incident beam of radiation passing throughthe lens. In a first condition, or mode, of the retroreflector, the lens 16 and the reflective part (18) are located relative to each other so that the incident beam of radiation (14) is retroreflected back to the detection unit. In a second condition, or mode, of the retroreflector (12), the lens (16) and the reflective part (18) are located relative to each other so that the reflected beam of radiation (22) is directed away from the detection unit.
摘要:
A backlight suitable for use in a display device includes an illumination device having at least one light source and a back reflector stack including a reflective layer and a transparent layer having substantially uniform refractive index and having a plurality of light-directing protrusions disposed in a matrix array. The transparent layer is disposed between the reflective layer and the illumination device with the plurality of light-directing protrusions facing away from the reflective layer. The plurality of light-directing protrusions are configured and disposed in a configuration that is not registered to any light source of the illumination device.

Interaktives Verpackungsmaterial bestehend aus einem Trägersubstrat, auf das ein Authentizitätsmerkmal aufgebracht ist, dadurch gekennzeichnet, dass das Authentizitätsmerkmal ein Druckbild und eine optisch aktive Struktur in Form eines Linsensystems aufweist.
摘要:
Encapsulated-lens retroreflective sheeting (10) is described which contains an improved binder layer (11). The binder layer (11) is obtained form a film-forming mixture which comprises: (A) a vinyl chloride copolymer, (B) a thermoplastic polyurethane, and (C) an aminoplast resin. Such binder layer (11) exhibits improved adhesion to metallized beads (14) and to a variety of cover films (15) such as acrylic films.
